Titanium powder

Titanium powder production

Our titanium powders include two different types of titanium powder and titanium hydride powder. Such titanium powders use high-quality titanium sponge as a material, and are manufactured gas-atomization or hydride-dehydrige processes. The properties of titanium powder give it a very wide range of uses. In particular, it is used as a material for powder metallurgy, or as a getter, and an application field is spreading steadily. The quality of our titanium powder has gained a high evaluation from users worldwide.

Types and properties of titanium powder types and properties

(1)Gas-atomized titanium powder

Gas-atomized titanium powder has registerded trademark, “TILOP” (Titanium Low Oxygen Powder). The powder is spherical and has low oxygen as one of its special properties.

(2)Ti-6Al-4V powder by gas atomized process

We have developed Ti-6Al-4V powder by gas atomized process.

(3)Titanium hydride-dehydride powder

Titanium sponge is difficult to be reduced directly to a powder, so the sponge is hydrogenated to be embrittled then after powdered. It is dehydrided again to form titanium hydride-dehydride powder. This powders is used as a material for powder metallurgy or getter materials for vacuum tubes, electron jars and stainless steel flasks that require a high vacuum.

(4)Titanium hydride powder

A powder made by hydrogenation and grinding of titanium sponge.
